City authorities have asked relevant agencies to halt construction on a section of a new road project in the western area of the former Thang Long citadel for archaeological research after various remnants of the old citadel were unearthed recently.

Nguyen Hoang Linh, deputy director of Ha Noi’s Traffic and Transportation Department, said that he had asked the management board of the construction project to co-ordinate with the Culture Heritage Department to help archaeologists conduct research at the site.

However, Linh confirmed that the project would only be stopped on the section of road thought to run over the royal citadel. The rest of the project would continue to meet the construction deadline.
